I am a Science and Chemistry teacher focused on Cambridge IGCSE and AS/A. I am also heavily involved in the National Chemistry Olympiad program. By way of background I have a PhD in inorganic chemistry and entered teaching after 13 years in the food industry. I guess I am a bit old fashioned - I don't use twitter and I have no idea what instagram or Pinterest are......but I love my subject and I love working with students.

Biology: Scientific English for Chinese Students - Ecology

(0)
This resource consists of * 2 worksheets with 3 pages of science terms we use to discuss and describe aspects of ecology. The student is asked to either fill in the correct English word or Chinese word when the opposite word is given. * A crossword (and answers) that uses some of the English words in the above worksheets * A worksheet in English with missing words that the student must fill in (answers are provided). My students tell me they enjoy using these resources because they can use them as references afterwards rather than gluing in their book and forgetting about them. The students also enjoy drawing pictures to help them learn these words. If you find any mistakes please contact me. The Chinese words have been checked by a native speaker though he is does not have a science background.

Tongan-English Science words used in physics and practical laboratory lessons

Tongan-English Science words used in physics and practical laboratory lessons

(0)
This resource contains key words that Tongan students will need to learn if they are to manage science lessons in physics and laboratory practical sessions. TESOL teachers will note that direct word for word translations are not easy and often multiple words are needed to explain a concept. I have used a Tongan teacher to help me with the translations. A key strategy I use is to ask the students to draw diagrams to help them explain what they mean.

Science: Tongan - The English words used in Astronomy lessons
DrogchemDrogchem

Science: Tongan - The English words used in Astronomy lessons

(0)
This resource consists of the list of key words used in Astronomy lessons (15-17 years old). Tongan students often come to Australia or New Zealand for further education but do not have support outside the TESOL class in terms of key Science words. Would you believe there is no word for spring tide? It requires a lengthy description. It is examples like this one which help illustrate why Tongan students often struggle in the English dominated classroom. Some cloze-style problems and a word finder are also included. Topics include tides, seasons and phases of the moon. This resource would help NZ students who are studying the Internal assessment AS 90954.

Physics: Scientific English for Korean Students - Learning and using the English words.

(0)
This resource focuses on the scientific words used in a typical physics class. There are multiple lists that are missing either the English of the Korean word. The lists include electricity, lab equipment, light and sound and typical physics words. Some worksheets focus on calculations and speaking/describing activities. These will be useful for Korean students studying abroad as international students or for teachers in Korea who wish to teach their students the English words typically used in a physics lesson. More problem based worksheets will be added to this resource in the next few weeks. The feedback from the classroom has been very positive and some colleagues from other schools have asked to use these resources for their Korean International students. If there are specific topics you would like please tell me as it is likely they are currently being developed / or used.

Chemistry: Periodic table made fun (12-15 year olds) - material for 3-4 weeks worth of teaching

Chemistry: Periodic table made fun (12-15 year olds) - material for 3-4 weeks worth of teaching

(2)
This resource consists of all of the material a teacher would need to teach a 3-4 week topic on this most delightful of topics: the Periodic table. Most of the focus is on the PT trends, how it can be used to predict a property of an element or charge on an ion. The activities have been tried in my class over the past few years and the students feedback and improved grades suggest they add value. My bug bear as a Chemist is that the PT is often taught as "first 20 by rote" with little time spent showing students how they can use the PT to help answer questions or solve problems. The topic covers subatomic particles, electron configuration, formation of ions, compounds/molecules, reactions of group 1 and 2 metals with group 6 and 7 non-metals and the tests for H2, O2 and CO2. Resources include worksheets, cloze activities, starters, projects, identifying equipment activity and short tests. The “notes for teachers” outlines how I teach this subject for both low and higher ability students along with ideas of the projects I set the students. Some documents contain more than 1 worksheet or activity and some worksheets are 2 pages long. Additional slides have been included on balancing equations if the class is stronger. Either use them in this course or save for the following year. Some of this material appears in other resources at Drogchem's shop (eg balancing equations and funworders). Thank you to everyone that bought this resource. If you get a spare 2 minutes could you leave some feedback? It is the only way I will know whether it meets your needs or what I might need to do to develop it further.

Genetics for yr 15-17 year olds

(0)
This resource includes a colour-coded power point pack (51 slides): the first half focuses on inheritance and how information is ultimately coded into proteins. The 2nd half covers sexual vs asexual reproduction, genetic variation, mono-hybrid inheritance, punnett squares, pedigree charts and natural selection. The slides are kept simple and are not cluttered with lots of words. The user can delete slides not required for their specific course. My students tell me the slides are easy to annotate and are very good for exam preparation. A set of learning objectives (SLOs) is given as well as three 2-page problem sheets that focused mainly on punnett squares and pedigree charts (answers provided). Two of the problem sheets can be bought separately from this shop ("Biology: punnet square problems and interpretation of pedigree charts"). Thank you to everyone who has bought this resource over the past year. If you have a spare 2 minutes could you please leave some feedback? This will help me refine or add to what I have published.
